General FAQs
Children should have their first orthodontic visit by age 7, as early assessment allows the orthodontist to identify potential issues while the jaw is still developing.
You should also consult an orthodontist at any age if you notice crooked, crowded, or misaligned teeth. At our Chatswood dental clinic, we provide expert guidance for both children and adults to ensure timely and effective orthodontic care.
Orthodontic treatment usually takes between 12 and 36 months, depending on the complexity of your case, your age, and the type of treatment used. Mild cases may take as little as six months, while more complex issues can take over three years.
At our Chatswood dental clinic, we provide personalized treatment plans to help patients achieve a straight, healthy smile in the optimal timeframe.
Both braces and clear aligners can cause mild, temporary discomfort, especially in the first few days or after adjustments. Traditional braces may irritate the mouth due to brackets and wires, while aligners usually create a gentle pressure as your teeth shift.
At our Chatswood dental clinic, we guide patients on how to manage discomfort and ensure orthodontic treatment is as comfortable as possible.
Yes, adults can get braces or clear aligners as long as their teeth and gums are healthy. Modern orthodontic options include traditional metal braces, ceramic braces, and nearly invisible clear aligners.
Many adults in Chatswood are choosing orthodontic treatment to improve their smile and oral health, and our dental clinic provides personalized solutions for patients of all ages.
Brush your teeth after every meal and at least twice a day with a soft-bristled toothbrush and fluoride toothpaste. Use interdental brushes or floss threaders to clean around braces. For aligners, rinse with lukewarm water and gently brush—avoid hot water or toothpaste.
Regular dental check-ups at our Chatswood clinic and avoiding hard, sticky, or sugary foods will help keep your teeth healthy and protect your orthodontic appliances.
